GEMET 3276N

IDENTIFICATION : Name printed GEMET 3276N

CLASSIFICATION :AWS/SFA 5.11 ENiCrMo4 DIN 1736 EL-NiMo 15Cr15W (2.4887)

CHARACTERISTICS :

Heavy coated ,basic type non-synthetic electrode depositing Ni-15 Cr-16 Mo-4W-5Fe weld metal. Carbon and Silicon are controlled to the very low levels so as to minimize carbide and intermediate phase precipitation.

APPLICATIONS :

  • Wrought alloys ASTM UNS N 10276
  • DIN 2.4819 (Ni Mo16 Cr 15W)
  • Haste alloy Alloy C-276(Haynes)
  • Inco Alloy C-276
  • ASTM A494 CW-12MW
  • ASTM A743, A744 CW-12M
  • Pumps, valves, pipe-work and vessels for use in aggressive environment in chemical process plants, equipment for fuel gas de-sulphurisation.

Redrying Temp : 300°C/2hrs
